5 of Illinois,f have invented new and useful Improvements in Percolators, of which the following is a specification.

This invention is an improved percolator adapted for use in an ordinary coifee pot and consists in the construction, com- The object of-myvinvention is to provide an improved percolator which is 'extremely 15 cheap andsimple and which is adapted to be used in any ordinary coffee pot and which does not require to be removedl from the' pot before pourin the coffee.

In the drawingszi re 1 is a vertical centralsectional View o my improved per- '.colator, -showing the same arranged in an ordinary 'coffee pot, for use in connection v therewith. Fig.v 2 is a detail plan of the cover for the percolating cup. Fi 3 is a detail transverse sectional View of t e same.

In accordance with m y invention, I ro- ;.vide an -upwardly tapermg tube 1 whic is provided at its lower lar er' end with a hollow foot or base 2 whic `is open on its under side. Thisl tube 'withits hollow base is adapted 'to 'be placed in an ordinary coffee pot so as to cause the hol ow base to rest onthe center of the bottom of the pot.

In connection with the percolator tube, I

provide-""'vavpercolatin cup 3 which has a central opening inits ottom through which the upper portlon of the tube extends. 'The provided the`u per end of the tube is secured the is removablefrom e spout and when attached to the upper end -of the tube is ar-v ranged -the u pery plortion ofthe cup. The cup 1s provi ed wit a detachable cover 6, the central portion of which is crowned as at .7 7 and is provided on its under side with a spreader or deector 8. This cover has; a, depending annular flange 9..which .is adapted to t in the uper end of the. cup

ear on vthe upper edge of the cup. When the cover is in place in the cup, its Bange 9 bears on the upper side-"of the perforated disk 5 and-holds the 56 latter place on the upper end ofthe tube.' The-cover-is provided with 'a series of radit gpecication o! Letters Patent.

ally and vertically arranged spring clamping/arms 11, the upper end of each of which 1s radial with respect to and is secured on the cover as at 12. These spring clamping' arms diverge downwardly and present straight portions 13 to bear against the inner side of the coffee pot near the upper end of the latter, the lower ends of the said Fspring clamping arms being inturned and extendin under the-bottom of the cup, as atf14. hese s ring clamping arms by projecting' radial y from the percolator and caring against the inner side of the upper portion of the coffee pot serve to posltlon the percolatorin the center of the coffee pot and owing to the downwardly inclined arrangement of the said spring clamping arms and the inclined sides of the coffee pot the said arms also serve to exert downwar pressure or tension on the percolator so as to normally keep the lower edge of the hol` low foot 2 in contact with the bottom of the coffee pot. The cover 6 has a pivotally mounted bail 15 which is adapted to be turned downwardly on the cover and also to be raised therefrom, this bail serving to enable the cover, together with .the other- -The o eration of my percolator is as follows he percolator 1s arran ed inthe center of the coffee ot with its oot 2bearing on the bottomt ereof, a suitable quantity of coffee is laced in the cup, the erforated disk is p aced on the upper en vof y the upwardly tapered tube and the cover 6 is then placed on the cup, the spring clampin arms 11 of the cover acting as hereinbeore stated to ho'ld thepercolator in place in the center'of the pot 'and to also press downwardly thereon. The water in the ot when raised to the boiling point is orced upwardly fromtime to time bysteam pressure through the ta ered tube, the spring clamping arms y13 yiel' ing under the steam pressure to permit.l water to enter the tube through the hollow ffoot 2 thereof, and as the water gushes upwardly from the upper end of the tube, it strikes and lis deflected by/the deflector 8 and falls in drops on the perforated disk and seethes down through` action ofthe spring 'clamping arms.

The various parts' o f my improved percolator may be made of any suitable material or materials and it will be understood that the same may be produced at small .cost. l While I have herein shown and described a preferred form of I ny invention, I would `have it understood vthat changes may be made'in the form, proportion and construction of the several parts without departing from the spirit of my invention and )within ,the scope of the appended claims.

I claim 4 1. A percolating attachment for a coffee pot comprising a percolator tube, a cup on the upper end of the tube into which Athe wardly and outwardly from the cup and adapted to engage the inner side of a coee potuto hold the percolatorin place therein.

2. A percolating attachment for a coffee pot comprising a perclator ltube, a cup on the upper end of the tube into which the latter discharges, a cover on the cup and radially and vertically arranged springs having their upper ends connected to the cover; the said springs extending downF wardly and outwardly from the cup and adapted to engage the inner Iside of a coifee pot to hold the percolator in place therein,`v

and the lower ends of the springs being bent under the bottom of the cup `to hold the cover thereof in place.

In testimony whereof l aix my signature in presence of .two Witnesses.
